EU SAVE Programme: Promotion of Energy Efficiency in Circulation Pumps, especially in Domestic Heating Systems

report

The EU SAVE II programme (Specific Actions for Vigorous Energy Efficiency) is the union-wide programme dedicated to promoting energy efficiency in industry, commerce and the domestic sector.

The circulation pump is one of the largest electricity consumers in the household. The electricity consumption of a circulation pump in a heating system may consume about approximately 500 to 600 kWh/year, particularly in the Middle and Northern European climate zone. This is comparable to the electricity consumption of a refrigerator or the lighting system in a house. Total electricity consumption of all EU circulation pumps in the residential sector is estimated at 40 TWh.

At the same time it is one of the least known electricity consumers in the home. Especially as the small circulation pump is seen as a low cost product and a "low involvement" product. For the end user, the investment cost of buying the circulator must be assumed to be the decisive argument for selection of a new pump, and not the energy consumption costs and they are not aware of the energy saving potential user. For instance for new "regulator" type circulation pumps payback times are in the order of 1 to 3 years and the EU electricity saving potential for this one particular energy saving product is significant.

Pump manufacturers are willing to bring energy efficient products on the market (both the new and replacement market), but find it difficult to re-educate or by pass the installer in their effort to make the end user more aware of the energy saving potential. For this they would need the development of a consistent EU policy and appropriate information measures by neutral governmental bodies and/or utilities.

The study aimed to provide the foundation for policy by creating an energy use information system for domestic hot water appliances, by providing factual information needed for measures such as e.g. EU energy labels and by making recommendations for their implementation. Three organisations, including a major pump manufacturer, worked together on this European Commission study sponsored under the SAVE II programme. The EU SAVE programme (Specific Actions for Vigorous Energy Efficiency) is the union-wide programme dedicated to promoting energy efficiency in industry, commerce and the domestic sector.

This project was funded by the EU SAVE II programme (Specific Actions for Vigorous Energy Efficiency), the union-wide programme dedicated to promoting energy efficiency in industry, commerce and the domestic sector.
